Teachings

Macedonius and his followers were semi-Arian, and taught that though the Son was eternal, He was not of one essense (Latin: consubstanciales, Greek: homoousios) with the Father but of like essense (Greek: homoiousios) with the Father. They also taught that the Holy Spirit was not eternal and consubstantial with the Father and the Son but a creation of the Father and an action of the Son. Thus, the Macedonians denied that the Holy Spirit was a hypostasis, or person, of the Holy Trinity.
